This paper presents an updated estimate of JUNO's sensitivity to neutrino mass ordering using the reactor antineutrinos emitted from eight nuclear reactor cores in the Taishan and Yangjiang nuclear power plants. This measurement is planned by studying the fine interference pattern caused by quasi-vacuum oscillations in the oscillated antineutrino spectrum at a baseline of 52.5~km and is completely independent of the CP violating phase and neutrino mixing angle $胃_{23}$. The sensitivity is obtained through a joint analysis of JUNO and Taishan Antineutrino Observatory (TAO) detectors utilizing the best available knowledge to date about the location and overburden of the JUNO experimental site, local and global nuclear reactors, JUNO and TAO detector responses, expected event rates and spectra of signals and backgrounds, and systematic uncertainties of analysis inputs. We find that a 3$蟽$ median sensitivity to reject the wrong mass ordering hypothesis can be reached with an exposure to approximately 6.5 years $\times$ 26.6 GW thermal power. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2405.18008v2-abstract-full').style.display = 'none'; document.getElementById('2405.18008v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 11 February, 2025; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 28 May, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> May 2024. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">The version published on Chinese Physics C</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2405.17860">arXiv:2405.17860</a> <span> [<a href="https://arxiv.org/pdf/2405.17860">pdf</a>, <a href="https://arxiv.org/format/2405.17860">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1088/1674-1137/ad83aa">10.1088/1674-1137/ad83aa <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Prediction of Energy Resolution in the JUNO Experiment </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/hep-ex?searchtype=author&query=JUNO+Collaboration"> JUNO Collaboration</a>, <a href="/search/hep-ex?searchtype=author&query=Abusleme%2C+A">Angel Abusleme</a>, <a href="/search/hep-ex?searchtype=author&query=Adam%2C+T">Thomas Adam</a>, <a href="/search/hep-ex?searchtype=author&query=Adamowicz%2C+K">Kai Adamowicz</a>, <a href="/search/hep-ex?searchtype=author&query=Ahmad%2C+S">Shakeel Ahmad</a>, <a href="/search/hep-ex?searchtype=author&query=Ahmed%2C+R">Rizwan Ahmed</a>, <a href="/search/hep-ex?searchtype=author&query=Aiello%2C+S">Sebastiano Aiello</a>, <a href="/search/hep-ex?searchtype=author&query=An%2C+F">Fengpeng An</a>, <a href="/search/hep-ex?searchtype=author&query=An%2C+Q">Qi An</a>, <a href="/search/hep-ex?searchtype=author&query=Andronico%2C+G">Giuseppe Andronico</a>, <a href="/search/hep-ex?searchtype=author&query=Anfimov%2C+N">Nikolay Anfimov</a>, <a href="/search/hep-ex?searchtype=author&query=Antonelli%2C+V">Vito Antonelli</a>, <a href="/search/hep-ex?searchtype=author&query=Antoshkina%2C+T">Tatiana Antoshkina</a>, <a href="/search/hep-ex?searchtype=author&query=de+Andr%C3%A9%2C+J+P+A+M">Jo茫o Pedro Athayde Marcondes de Andr茅</a>, <a href="/search/hep-ex?searchtype=author&query=Auguste%2C+D">Didier Auguste</a>, <a href="/search/hep-ex?searchtype=author&query=Bai%2C+W">Weidong Bai</a>, <a href="/search/hep-ex?searchtype=author&query=Balashov%2C+N">Nikita Balashov</a>, <a href="/search/hep-ex?searchtype=author&query=Baldini%2C+W">Wander Baldini</a>, <a href="/search/hep-ex?searchtype=author&query=Barresi%2C+A">Andrea Barresi</a>, <a href="/search/hep-ex?searchtype=author&query=Basilico%2C+D">Davide Basilico</a>, <a href="/search/hep-ex?searchtype=author&query=Baussan%2C+E">Eric Baussan</a>, <a href="/search/hep-ex?searchtype=author&query=Bellato%2C+M">Marco Bellato</a>, <a href="/search/hep-ex?searchtype=author&query=Beretta%2C+M">Marco Beretta</a>, <a href="/search/hep-ex?searchtype=author&query=Bergnoli%2C+A">Antonio Bergnoli</a>, <a href="/search/hep-ex?searchtype=author&query=Bick%2C+D">Daniel Bick</a> , et al.

The determination of neutrino mass ordering in JUNO requires an exceptional energy resolution better than 3\% at 1~MeV. To achieve this ambitious goal, significant efforts have been undertaken in the design and production of the key components of the JUNO detector. Various factors affecting the detection of inverse beta decay signals have an impact on the energy resolution, extending beyond the statistical fluctuations of the detected number of photons, such as the properties of the liquid scintillator, performance of photomultiplier tubes, and the energy reconstruction algorithm. To account for these effects, a full JUNO simulation and reconstruction approach is employed. This enables the modeling of all relevant effects and the evaluation of associated inputs to accurately estimate the energy resolution. The results of study reveal an energy resolution of 2.95\% at 1~MeV. Furthermore, this study assesses the contribution of major effects to the overall energy resolution budget.

The invisible decays of $s$-shell neutrons in $^{12}{\rm C}$ will leave a highly excited residual nucleus. Subsequently, some de-excitation modes of the excited residual nuclei can produce a time- and space-correlated triple coincidence signal in the JUNO detector. Based on a full Monte Carlo simulation informed with the latest available data, we estimate all backgrounds, including inverse beta decay events of the reactor antineutrino $\bar谓_e$, natural radioactivity, cosmogenic isotopes and neutral current interactions of atmospheric neutrinos. Pulse shape discrimination and multivariate analysis techniques are employed to further suppress backgrounds. With two years of exposure, JUNO is expected to give an order of magnitude improvement compared to the current best limits. After 10 years of data taking, the JUNO expected sensitivities at a 90% confidence level are $蟿/B( n \rightarrow { inv} ) > 5.0 \times 10^{31} \, {\rm yr}$ and $蟿/B( nn \rightarrow { inv} ) > 1.4 \times 10^{32} \, {\rm yr}$. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2405.17792v1-abstract-full').style.display = 'none'; document.getElementById('2405.17792v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 27 May, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> May 2024. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">28 pages, 7 figures, 4 tables</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2309.07109">arXiv:2309.07109</a> <span> [<a href="https://arxiv.org/pdf/2309.07109">pdf</a>, <a href="https://arxiv.org/ps/2309.07109">ps</a>, <a href="https://arxiv.org/format/2309.07109">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Astrophysical Phenomena">astro-ph.HE</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Phenomenology">hep-ph</span> </div> </div> <p class="title is-5 mathjax"> Real-time Monitoring for the Next Core-Collapse Supernova in JUNO </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/hep-ex?searchtype=author&query=Abusleme%2C+A">Angel Abusleme</a>, <a href="/search/hep-ex?searchtype=author&query=Adam%2C+T">Thomas Adam</a>, <a href="/search/hep-ex?searchtype=author&query=Ahmad%2C+S">Shakeel Ahmad</a>, <a href="/search/hep-ex?searchtype=author&query=Ahmed%2C+R">Rizwan Ahmed</a>, <a href="/search/hep-ex?searchtype=author&query=Aiello%2C+S">Sebastiano Aiello</a>, <a href="/search/hep-ex?searchtype=author&query=Akram%2C+M">Muhammad Akram</a>, <a href="/search/hep-ex?searchtype=author&query=Aleem%2C+A">Abid Aleem</a>, <a href="/search/hep-ex?searchtype=author&query=An%2C+F">Fengpeng An</a>, <a href="/search/hep-ex?searchtype=author&query=An%2C+Q">Qi An</a>, <a href="/search/hep-ex?searchtype=author&query=Andronico%2C+G">Giuseppe Andronico</a>, <a href="/search/hep-ex?searchtype=author&query=Anfimov%2C+N">Nikolay Anfimov</a>, <a href="/search/hep-ex?searchtype=author&query=Antonelli%2C+V">Vito Antonelli</a>, <a href="/search/hep-ex?searchtype=author&query=Antoshkina%2C+T">Tatiana Antoshkina</a>, <a href="/search/hep-ex?searchtype=author&query=Asavapibhop%2C+B">Burin Asavapibhop</a>, <a href="/search/hep-ex?searchtype=author&query=de+Andr%C3%A9%2C+J+P+A+M">Jo茫o Pedro Athayde Marcondes de Andr茅</a>, <a href="/search/hep-ex?searchtype=author&query=Auguste%2C+D">Didier Auguste</a>, <a href="/search/hep-ex?searchtype=author&query=Bai%2C+W">Weidong Bai</a>, <a href="/search/hep-ex?searchtype=author&query=Balashov%2C+N">Nikita Balashov</a>, <a href="/search/hep-ex?searchtype=author&query=Baldini%2C+W">Wander Baldini</a>, <a href="/search/hep-ex?searchtype=author&query=Barresi%2C+A">Andrea Barresi</a>, <a href="/search/hep-ex?searchtype=author&query=Basilico%2C+D">Davide Basilico</a>, <a href="/search/hep-ex?searchtype=author&query=Baussan%2C+E">Eric Baussan</a>, <a href="/search/hep-ex?searchtype=author&query=Bellato%2C+M">Marco Bellato</a>, <a href="/search/hep-ex?searchtype=author&query=Beretta%2C+M">Marco Beretta</a>, <a href="/search/hep-ex?searchtype=author&query=Bergnoli%2C+A">Antonio Bergnoli</a> , et al.

The early and prompt detection of neutrinos before (pre-SN) and during the supernova (SN) burst presents a unique opportunity for multi-messenger observations of CCSN events. In this study, we describe the monitoring concept and present the sensitivity of the system to pre-SN and SN neutrinos at the Jiangmen Underground Neutrino Observatory (JUNO), a 20 kton liquid scintillator detector currently under construction in South China. The real-time monitoring system is designed to ensure both prompt alert speed and comprehensive coverage of progenitor stars. It incorporates prompt monitors on the electronic board as well as online monitors at the data acquisition stage. Assuming a false alert rate of 1 per year, this monitoring system exhibits sensitivity to pre-SN neutrinos up to a distance of approximately 1.6 (0.9) kiloparsecs and SN neutrinos up to about 370 (360) kiloparsecs for a progenitor mass of 30 solar masses, considering both normal and inverted mass ordering scenarios. The pointing ability of the CCSN is evaluated by analyzing the accumulated event anisotropy of inverse beta decay interactions from pre-SN or SN neutrinos. This, along with the early alert, can play a crucial role in facilitating follow-up multi-messenger observations of the next galactic or nearby extragalactic CCSN. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2309.07109v2-abstract-full').style.display = 'none'; document.getElementById('2309.07109v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 4 December, 2023; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 13 September, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> September 2023. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">24 pages, 9 figures, accepted for the publication at JCAP</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2306.09567">arXiv:2306.09567</a> <span> [<a href="https://arxiv.org/pdf/2306.09567">pdf</a>, <a href="https://arxiv.org/format/2306.09567">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Astrophysical Phenomena">astro-ph.HE</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Phenomenology">hep-ph</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1088/1475-7516/2023/09/001">10.1088/1475-7516/2023/09/001 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> JUNO sensitivity to the annihilation of MeV dark matter in the galactic halo </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/hep-ex?searchtype=author&query=JUNO+Collaboration"> JUNO Collaboration</a>, <a href="/search/hep-ex?searchtype=author&query=Abusleme%2C+A">Angel Abusleme</a>, <a href="/search/hep-ex?searchtype=author&query=Adam%2C+T">Thomas Adam</a>, <a href="/search/hep-ex?searchtype=author&query=Ahmad%2C+S">Shakeel Ahmad</a>, <a href="/search/hep-ex?searchtype=author&query=Ahmed%2C+R">Rizwan Ahmed</a>, <a href="/search/hep-ex?searchtype=author&query=Aiello%2C+S">Sebastiano Aiello</a>, <a href="/search/hep-ex?searchtype=author&query=Akram%2C+M">Muhammad Akram</a>, <a href="/search/hep-ex?searchtype=author&query=Aleem%2C+A">Abid Aleem</a>, <a href="/search/hep-ex?searchtype=author&query=Alexandros%2C+T">Tsagkarakis Alexandros</a>, <a href="/search/hep-ex?searchtype=author&query=An%2C+F">Fengpeng An</a>, <a href="/search/hep-ex?searchtype=author&query=An%2C+Q">Qi An</a>, <a href="/search/hep-ex?searchtype=author&query=Andronico%2C+G">Giuseppe Andronico</a>, <a href="/search/hep-ex?searchtype=author&query=Anfimov%2C+N">Nikolay Anfimov</a>, <a href="/search/hep-ex?searchtype=author&query=Antonelli%2C+V">Vito Antonelli</a>, <a href="/search/hep-ex?searchtype=author&query=Antoshkina%2C+T">Tatiana Antoshkina</a>, <a href="/search/hep-ex?searchtype=author&query=Asavapibhop%2C+B">Burin Asavapibhop</a>, <a href="/search/hep-ex?searchtype=author&query=de+Andr%C3%A9%2C+J+P+A+M">Jo茫o Pedro Athayde Marcondes de Andr茅</a>, <a href="/search/hep-ex?searchtype=author&query=Auguste%2C+D">Didier Auguste</a>, <a href="/search/hep-ex?searchtype=author&query=Bai%2C+W">Weidong Bai</a>, <a href="/search/hep-ex?searchtype=author&query=Balashov%2C+N">Nikita Balashov</a>, <a href="/search/hep-ex?searchtype=author&query=Baldini%2C+W">Wander Baldini</a>, <a href="/search/hep-ex?searchtype=author&query=Barresi%2C+A">Andrea Barresi</a>, <a href="/search/hep-ex?searchtype=author&query=Basilico%2C+D">Davide Basilico</a>, <a href="/search/hep-ex?searchtype=author&query=Baussan%2C+E">Eric Baussan</a>, <a href="/search/hep-ex?searchtype=author&query=Bellato%2C+M">Marco Bellato</a> , et al.

This muon tracker will help to evaluate the contribution of the cosmogenic background to the signal. The Top Tracker is located above JUNO's water Cherenkov Detector and Central Detector, covering about 60% of the surface above them. The JUNO Top Tracker is constituted by the decommissioned OPERA experiment Target Tracker modules. The technology used consists in walls of two planes of plastic scintillator strips, one per transverse direction. Wavelength shifting fibres collect the light signal emitted by the scintillator strips and guide it to both ends where it is read by multianode photomultiplier tubes. Compared to the OPERA Target Tracker, the JUNO Top Tracker uses new electronics able to cope with the high rate produced by the high rock radioactivity compared to the one in Gran Sasso underground laboratory. This paper will present the new electronics and mechanical structure developed for the Top Tracker of JUNO along with its expected performance based on the current detector simulation. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2303.05172v1-abstract-full').style.display = 'none'; document.getElementById('2303.05172v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 9 March, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> March 2023. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">20 pages</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Nucl.Instrum.Meth.A 1057 (2023) 168680 </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2303.03910">arXiv:2303.03910</a> <span> [<a href="https://arxiv.org/pdf/2303.03910">pdf</a>, <a href="https://arxiv.org/format/2303.03910">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> </div> </div> <p class="title is-5 mathjax"> JUNO sensitivity to $^7$Be, $pep$, and CNO solar neutrinos </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/hep-ex?searchtype=author&query=Abusleme%2C+A">Angel Abusleme</a>, <a href="/search/hep-ex?searchtype=author&query=Adam%2C+T">Thomas Adam</a>, <a href="/search/hep-ex?searchtype=author&query=Ahmad%2C+S">Shakeel Ahmad</a>, <a href="/search/hep-ex?searchtype=author&query=Ahmed%2C+R">Rizwan Ahmed</a>, <a href="/search/hep-ex?searchtype=author&query=Aiello%2C+S">Sebastiano Aiello</a>, <a href="/search/hep-ex?searchtype=author&query=Akram%2C+M">Muhammad Akram</a>, <a href="/search/hep-ex?searchtype=author&query=Aleem%2C+A">Abid Aleem</a>, <a href="/search/hep-ex?searchtype=author&query=Alexandros%2C+T">Tsagkarakis Alexandros</a>, <a href="/search/hep-ex?searchtype=author&query=An%2C+F">Fengpeng An</a>, <a href="/search/hep-ex?searchtype=author&query=An%2C+Q">Qi An</a>, <a href="/search/hep-ex?searchtype=author&query=Andronico%2C+G">Giuseppe Andronico</a>, <a href="/search/hep-ex?searchtype=author&query=Anfimov%2C+N">Nikolay Anfimov</a>, <a href="/search/hep-ex?searchtype=author&query=Antonelli%2C+V">Vito Antonelli</a>, <a href="/search/hep-ex?searchtype=author&query=Antoshkina%2C+T">Tatiana Antoshkina</a>, <a href="/search/hep-ex?searchtype=author&query=Asavapibhop%2C+B">Burin Asavapibhop</a>, <a href="/search/hep-ex?searchtype=author&query=de+Andr%C3%A9%2C+J+P+A+M">Jo茫o Pedro Athayde Marcondes de Andr茅</a>, <a href="/search/hep-ex?searchtype=author&query=Auguste%2C+D">Didier Auguste</a>, <a href="/search/hep-ex?searchtype=author&query=Bai%2C+W">Weidong Bai</a>, <a href="/search/hep-ex?searchtype=author&query=Balashov%2C+N">Nikita Balashov</a>, <a href="/search/hep-ex?searchtype=author&query=Baldini%2C+W">Wander Baldini</a>, <a href="/search/hep-ex?searchtype=author&query=Barresi%2C+A">Andrea Barresi</a>, <a href="/search/hep-ex?searchtype=author&query=Basilico%2C+D">Davide Basilico</a>, <a href="/search/hep-ex?searchtype=author&query=Baussan%2C+E">Eric Baussan</a>, <a href="/search/hep-ex?searchtype=author&query=Bellato%2C+M">Marco Bellato</a>, <a href="/search/hep-ex?searchtype=author&query=Beretta%2C+M">Marco Beretta</a> , et al.

JUNO's large target mass and excellent energy resolution are prerequisites for reaching unprecedented levels of precision. In this paper, we provide estimation of the JUNO sensitivity to 7Be, pep, and CNO solar neutrinos that can be obtained via a spectral analysis above the 0.45 MeV threshold. This study is performed assuming different scenarios of the liquid scintillator radiopurity, ranging from the most opti mistic one corresponding to the radiopurity levels obtained by the Borexino experiment, up to the minimum requirements needed to perform the neutrino mass ordering determination with reactor antineutrinos - the main goal of JUNO. Our study shows that in most scenarios, JUNO will be able to improve the current best measurements on 7Be, pep, and CNO solar neutrino fluxes. We also perform a study on the JUNO capability to detect periodical time variations in the solar neutrino flux, such as the day-night modulation induced by neutrino flavor regeneration in Earth, and the modulations induced by temperature changes driven by helioseismic waves. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2303.03910v1-abstract-full').style.display = 'none'; document.getElementById('2303.03910v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 7 March, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> March 2023. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2302.01666">arXiv:2302.01666</a> <span> [<a href="https://arxiv.org/pdf/2302.01666">pdf</a>, <a href="https://arxiv.org/format/2302.01666">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1016/j.nima.2023.168103">10.1016/j.nima.2023.168103 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> The Analytical Method algorithm for trigger primitives generation at the LHC Drift Tubes detector </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/hep-ex?searchtype=author&query=Abbiendi%2C+G">G.

Due to the increase of occupancy, trigger latency and rates, the full electronics of the CMS Drift Tube (DT) chambers will need to be replaced. In the new design, the time bin for the digitisation of the chamber signals will be of around 1~ns, and the totality of the signals will be forwarded asynchronously to the service cavern at full resolution. The new backend system will be in charge of building the trigger primitives of each chamber. These trigger primitives contain the information at chamber level about the muon candidates position, direction, and collision time, and are used as input in the L1 CMS trigger. The added functionalities will improve the robustness of the system against ageing. An algorithm based on analytical solutions for reconstructing the DT trigger primitives, called Analytical Method, has been implemented both as a software C++ emulator and in firmware. Its performance has been estimated using the software emulator with simulated and real data samples, and through hardware implementation tests. Measured efficiencies are 96 to 98\% for all qualities and time and spatial resolutions are close to the ultimate performance of the DT chambers. A prototype chain of the HL-LHC electronics using the Analytical Method for trigger primitive generation has been installed during Long Shutdown 2 of the LHC and operated in CMS cosmic data taking campaigns in 2020 and 2021. Results from this validation step, the so-called Slice Test, are presented. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2302.01666v1-abstract-full').style.display = 'none'; document.getElementById('2302.01666v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 3 February, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> February 2023. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">16 pages, 11 figures</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2212.08502">arXiv:2212.08502</a> <span> [<a href="https://arxiv.org/pdf/2212.08502">pdf</a>, <a href="https://arxiv.org/format/2212.08502">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Phenomenology">hep-ph</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1088/1674-1137/ace9c6">10.1088/1674-1137/ace9c6 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> JUNO Sensitivity on Proton Decay $p\to \bar谓K^+$ Searches </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/hep-ex?searchtype=author&query=JUNO+Collaboration"> JUNO Collaboration</a>, <a href="/search/hep-ex?searchtype=author&query=Abusleme%2C+A">Angel Abusleme</a>, <a href="/search/hep-ex?searchtype=author&query=Adam%2C+T">Thomas Adam</a>, <a href="/search/hep-ex?searchtype=author&query=Ahmad%2C+S">Shakeel Ahmad</a>, <a href="/search/hep-ex?searchtype=author&query=Ahmed%2C+R">Rizwan Ahmed</a>, <a href="/search/hep-ex?searchtype=author&query=Aiello%2C+S">Sebastiano Aiello</a>, <a href="/search/hep-ex?searchtype=author&query=Akram%2C+M">Muhammad Akram</a>, <a href="/search/hep-ex?searchtype=author&query=An%2C+F">Fengpeng An</a>, <a href="/search/hep-ex?searchtype=author&query=An%2C+Q">Qi An</a>, <a href="/search/hep-ex?searchtype=author&query=Andronico%2C+G">Giuseppe Andronico</a>, <a href="/search/hep-ex?searchtype=author&query=Anfimov%2C+N">Nikolay Anfimov</a>, <a href="/search/hep-ex?searchtype=author&query=Antonelli%2C+V">Vito Antonelli</a>, <a href="/search/hep-ex?searchtype=author&query=Antoshkina%2C+T">Tatiana Antoshkina</a>, <a href="/search/hep-ex?searchtype=author&query=Asavapibhop%2C+B">Burin Asavapibhop</a>, <a href="/search/hep-ex?searchtype=author&query=de+Andr%C3%A9%2C+J+P+A+M">Jo茫o Pedro Athayde Marcondes de Andr茅</a>, <a href="/search/hep-ex?searchtype=author&query=Auguste%2C+D">Didier Auguste</a>, <a href="/search/hep-ex?searchtype=author&query=Balashov%2C+N">Nikita Balashov</a>, <a href="/search/hep-ex?searchtype=author&query=Baldini%2C+W">Wander Baldini</a>, <a href="/search/hep-ex?searchtype=author&query=Barresi%2C+A">Andrea Barresi</a>, <a href="/search/hep-ex?searchtype=author&query=Basilico%2C+D">Davide Basilico</a>, <a href="/search/hep-ex?searchtype=author&query=Baussan%2C+E">Eric Baussan</a>, <a href="/search/hep-ex?searchtype=author&query=Bellato%2C+M">Marco Bellato</a>, <a href="/search/hep-ex?searchtype=author&query=Bergnoli%2C+A">Antonio Bergnoli</a>, <a href="/search/hep-ex?searchtype=author&query=Birkenfeld%2C+T">Thilo Birkenfeld</a>, <a href="/search/hep-ex?searchtype=author&query=Blin%2C+S">Sylvie Blin</a> , et al.

In this paper, the potential on searching for proton decay in $p\to \bar谓K^+$ mode with JUNO is investigated.The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits to suppress the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar谓K^+$ is 36.9% with a background level of 0.2 events after 10 years of data taking. The estimated sensitivity based on 200 kton-years exposure is $9.6 \times 10^{33}$ years, competitive with the current best limits on the proton lifetime in this channel. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2212.08502v3-abstract-full').style.display = 'none'; document.getElementById('2212.08502v3-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 26 October, 2023; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 16 December, 2022; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> December 2022. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">14 pages, 12 figures, an author added</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2212.08454">arXiv:2212.08454</a> <span> [<a href="https://arxiv.org/pdf/2212.08454">pdf</a>, <a href="https://arxiv.org/format/2212.08454">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1016/j.nima.2023.168322">10.1016/j.nima.2023.168322 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Validation and integration tests of the JUNO 20-inch PMTs readout electronics </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/hep-ex?searchtype=author&query=Cerrone%2C+V">Vanessa Cerrone</a>, <a href="/search/hep-ex?searchtype=author&query=von+Sturm%2C+K">Katharina von Sturm</a>, <a href="/search/hep-ex?searchtype=author&query=Bellato%2C+M">Marco Bellato</a>, <a href="/search/hep-ex?searchtype=author&query=Bergnoli%2C+A">Antonio Bergnoli</a>, <a href="/search/hep-ex?searchtype=author&query=Bolognesi%2C+M">Matteo Bolognesi</a>, <a href="/search/hep-ex?searchtype=author&query=Brugnera%2C+R">Riccardo Brugnera</a>, <a href="/search/hep-ex?searchtype=author&query=Chen%2C+C">Chao Chen</a>, <a href="/search/hep-ex?searchtype=author&query=Clerbaux%2C+B">Barbara Clerbaux</a>, <a href="/search/hep-ex?searchtype=author&query=Coppi%2C+A">Alberto Coppi</a>, <a href="/search/hep-ex?searchtype=author&query=Corso%2C+F+d">Flavio dal Corso</a>, <a href="/search/hep-ex?searchtype=author&query=Corti%2C+D">Daniele Corti</a>, <a href="/search/hep-ex?searchtype=author&query=Dong%2C+J">Jianmeng Dong</a>, <a href="/search/hep-ex?searchtype=author&query=Dou%2C+W">Wei Dou</a>, <a href="/search/hep-ex?searchtype=author&query=Fan%2C+L">Lei Fan</a>, <a href="/search/hep-ex?searchtype=author&query=Garfagnini%2C+A">Alberto Garfagnini</a>, <a href="/search/hep-ex?searchtype=author&query=Gong%2C+G">Guanghua Gong</a>, <a href="/search/hep-ex?searchtype=author&query=Grassi%2C+M">Marco Grassi</a>, <a href="/search/hep-ex?searchtype=author&query=Hang%2C+S">Shuang Hang</a>, <a href="/search/hep-ex?searchtype=author&query=Guizzetti%2C+R+M">Rosa Maria Guizzetti</a>, <a href="/search/hep-ex?searchtype=author&query=He%2C+C">Cong He</a>, <a href="/search/hep-ex?searchtype=author&query=Hu%2C+J">Jun Hu</a>, <a href="/search/hep-ex?searchtype=author&query=Isocrate%2C+R">Roberto Isocrate</a>, <a href="/search/hep-ex?searchtype=author&query=Jelmini%2C+B">Beatrice Jelmini</a>, <a href="/search/hep-ex?searchtype=author&query=Ji%2C+X">Xiaolu Ji</a>, <a href="/search/hep-ex?searchtype=author&query=Jiang%2C+X">Xiaoshan Jiang</a> , et al.

The present paper describes the tests performed on the readout modules to measure their performances. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2212.08454v1-abstract-full').style.display = 'none'; document.getElementById('2212.08454v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 16 December, 2022; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> December 2022. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">20 pages, 13 figures</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2210.08437">arXiv:2210.08437</a> <span> [<a href="https://arxiv.org/pdf/2210.08437">pdf</a>, <a href="https://arxiv.org/format/2210.08437">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Solar and Stellar Astrophysics">astro-ph.SR</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Phenomenology">hep-ph</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Nuclear Experiment">nucl-ex</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.3847/1538-4357/ad2bfd">10.3847/1538-4357/ad2bfd <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Model Independent Approach of the JUNO $^8$B Solar Neutrino Program </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/hep-ex?searchtype=author&query=JUNO+Collaboration"> JUNO Collaboration</a>, <a href="/search/hep-ex?searchtype=author&query=Zhao%2C+J">Jie Zhao</a>, <a href="/search/hep-ex?searchtype=author&query=Yue%2C+B">Baobiao Yue</a>, <a href="/search/hep-ex?searchtype=author&query=Lu%2C+H">Haoqi Lu</a>, <a href="/search/hep-ex?searchtype=author&query=Li%2C+Y">Yufeng Li</a>, <a href="/search/hep-ex?searchtype=author&query=Ling%2C+J">Jiajie Ling</a>, <a href="/search/hep-ex?searchtype=author&query=Yu%2C+Z">Zeyuan Yu</a>, <a href="/search/hep-ex?searchtype=author&query=Abusleme%2C+A">Angel Abusleme</a>, <a href="/search/hep-ex?searchtype=author&query=Adam%2C+T">Thomas Adam</a>, <a href="/search/hep-ex?searchtype=author&query=Ahmad%2C+S">Shakeel Ahmad</a>, <a href="/search/hep-ex?searchtype=author&query=Ahmed%2C+R">Rizwan Ahmed</a>, <a href="/search/hep-ex?searchtype=author&query=Aiello%2C+S">Sebastiano Aiello</a>, <a href="/search/hep-ex?searchtype=author&query=Akram%2C+M">Muhammad Akram</a>, <a href="/search/hep-ex?searchtype=author&query=Aleem%2C+A">Abid Aleem</a>, <a href="/search/hep-ex?searchtype=author&query=Alexandros%2C+T">Tsagkarakis Alexandros</a>, <a href="/search/hep-ex?searchtype=author&query=An%2C+F">Fengpeng An</a>, <a href="/search/hep-ex?searchtype=author&query=An%2C+Q">Qi An</a>, <a href="/search/hep-ex?searchtype=author&query=Andronico%2C+G">Giuseppe Andronico</a>, <a href="/search/hep-ex?searchtype=author&query=Anfimov%2C+N">Nikolay Anfimov</a>, <a href="/search/hep-ex?searchtype=author&query=Antonelli%2C+V">Vito Antonelli</a>, <a href="/search/hep-ex?searchtype=author&query=Antoshkina%2C+T">Tatiana Antoshkina</a>, <a href="/search/hep-ex?searchtype=author&query=Asavapibhop%2C+B">Burin Asavapibhop</a>, <a href="/search/hep-ex?searchtype=author&query=de+Andr%C3%A9%2C+J+P+A+M">Jo茫o Pedro Athayde Marcondes de Andr茅</a>, <a href="/search/hep-ex?searchtype=author&query=Auguste%2C+D">Didier Auguste</a>, <a href="/search/hep-ex?searchtype=author&query=Bai%2C+W">Weidong Bai</a> , et al.

Due to the largest-ever mass of $^{13}$C nuclei in the liquid-scintillator detectors and the {expected} low background level, $^8$B solar neutrinos would be observable in the CC and NC interactions on $^{13}$C for the first time. By virtue of optimized event selections and muon veto strategies, backgrounds from the accidental coincidence, muon-induced isotopes, and external backgrounds can be greatly suppressed. Excellent signal-to-background ratios can be achieved in the CC, NC and ES channels to guarantee the $^8$B solar neutrino observation. From the sensitivity studies performed in this work, we show that JUNO, with ten years of data, can reach the {1$蟽$} precision levels of 5%, 8% and 20% for the $^8$B neutrino flux, $\sin^2胃_{12}$, and $螖m^2_{21}$, respectively. It would be unique and helpful to probe the details of both solar physics and neutrino physics. In addition, when combined with SNO, the world-best precision of 3% is expected for the $^8$B neutrino flux measurement. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2210.08437v2-abstract-full').style.display = 'none'; document.getElementById('2210.08437v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 6 March, 2024; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 15 October, 2022; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> October 2022. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">19 pages, 7 figures, accepted version to appear in The Astrophysical Journal.

We employ the latest information on the DSNB flux predictions, and investigate in detail the background and its reduction for the DSNB search at JUNO. The atmospheric neutrino induced neutral current (NC) background turns out to be the most critical background, whose uncertainty is carefully evaluated from both the spread of model predictions and an envisaged \textit{in situ} measurement. We also make a careful study on the background suppression with the pulse shape discrimination (PSD) and triple coincidence (TC) cuts. With latest DSNB signal predictions, more realistic background evaluation and PSD efficiency optimization, and additional TC cut, JUNO can reach the significance of 3$蟽$ for 3 years of data taking, and achieve better than 5$蟽$ after 10 years for a reference DSNB model. In the pessimistic scenario of non-observation, JUNO would strongly improve the limits and exclude a significant region of the model parameter space. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2205.08830v2-abstract-full').style.display = 'none'; document.getElementById('2205.08830v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 13 October, 2022; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 18 May, 2022; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> May 2022. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">29 pages, 11 figures, final published version in JCAP</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> JCAP 10 (2022) 033 </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2205.08629">arXiv:2205.08629</a> <span> [<a href="https://arxiv.org/pdf/2205.08629">pdf</a>, <a href="https://arxiv.org/format/2205.08629">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1140/epjc/s10052-022-11002-8">10.1140/epjc/s10052-022-11002-8 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Mass Testing and Characterization of 20-inch PMTs for JUNO </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/hep-ex?searchtype=author&query=Abusleme%2C+A">Angel Abusleme</a>, <a href="/search/hep-ex?searchtype=author&query=Adam%2C+T">Thomas Adam</a>, <a href="/search/hep-ex?searchtype=author&query=Ahmad%2C+S">Shakeel Ahmad</a>, <a href="/search/hep-ex?searchtype=author&query=Ahmed%2C+R">Rizwan Ahmed</a>, <a href="/search/hep-ex?searchtype=author&query=Aiello%2C+S">Sebastiano Aiello</a>, <a href="/search/hep-ex?searchtype=author&query=Akram%2C+M">Muhammad Akram</a>, <a href="/search/hep-ex?searchtype=author&query=Aleem%2C+A">Abid Aleem</a>, <a href="/search/hep-ex?searchtype=author&query=Alexandros%2C+T">Tsagkarakis Alexandros</a>, <a href="/search/hep-ex?searchtype=author&query=An%2C+F">Fengpeng An</a>, <a href="/search/hep-ex?searchtype=author&query=An%2C+Q">Qi An</a>, <a href="/search/hep-ex?searchtype=author&query=Andronico%2C+G">Giuseppe Andronico</a>, <a href="/search/hep-ex?searchtype=author&query=Anfimov%2C+N">Nikolay Anfimov</a>, <a href="/search/hep-ex?searchtype=author&query=Antonelli%2C+V">Vito Antonelli</a>, <a href="/search/hep-ex?searchtype=author&query=Antoshkina%2C+T">Tatiana Antoshkina</a>, <a href="/search/hep-ex?searchtype=author&query=Asavapibhop%2C+B">Burin Asavapibhop</a>, <a href="/search/hep-ex?searchtype=author&query=de+Andre%2C+J+P+A+M">Joao Pedro Athayde Marcondes de Andre</a>, <a href="/search/hep-ex?searchtype=author&query=Auguste%2C+D">Didier Auguste</a>, <a href="/search/hep-ex?searchtype=author&query=Bai%2C+W">Weidong Bai</a>, <a href="/search/hep-ex?searchtype=author&query=Balashov%2C+N">Nikita Balashov</a>, <a href="/search/hep-ex?searchtype=author&query=Baldini%2C+W">Wander Baldini</a>, <a href="/search/hep-ex?searchtype=author&query=Barresi%2C+A">Andrea Barresi</a>, <a href="/search/hep-ex?searchtype=author&query=Basilico%2C+D">Davide Basilico</a>, <a href="/search/hep-ex?searchtype=author&query=Baussan%2C+E">Eric Baussan</a>, <a href="/search/hep-ex?searchtype=author&query=Bellato%2C+M">Marco Bellato</a>, <a href="/search/hep-ex?searchtype=author&query=Bergnoli%2C+A">Antonio Bergnoli</a> , et al.

Its key feature is an excellent energy resolution of at least 3 % at 1 MeV, for which its instruments need to meet a certain quality and thus have to be fully characterized. More than 20,000 20-inch PMTs have been received and assessed by JUNO after a detailed testing program which began in 2017 and elapsed for about four years. Based on this mass characterization and a set of specific requirements, a good quality of all accepted PMTs could be ascertained. This paper presents the performed testing procedure with the designed testing systems as well as the statistical characteristics of all 20-inch PMTs intended to be used in the JUNO experiment, covering more than fifteen performance parameters including the photocathode uniformity. This constitutes the largest sample of 20-inch PMTs ever produced and studied in detail to date, i.e. 15,000 of the newly developed 20-inch MCP-PMTs from Northern Night Vision Technology Co. (NNVT) and 5,000 of dynode PMTs from Hamamatsu Photonics K.

This publication presents new sensitivity estimates for the measurement of the $螖m^2_{31}$, $螖m^2_{21}$, $\sin^2 胃_{12}$, and $\sin^2 胃_{13}$ oscillation parameters using reactor antineutrinos, which is one of the primary physics goals of the experiment. The sensitivities are obtained using the best knowledge available to date on the location and overburden of the experimental site, the nuclear reactors in the surrounding area and beyond, the detector response uncertainties, and the reactor antineutrino spectral shape constraints expected from the TAO satellite detector. It is found that the $螖m^2_{31}$, $螖m^2_{21}$, and $\sin^2 胃_{12}$ oscillation parameters will be determined to better than 0.5% precision in six years of data collection, which represents approximately an order of magnitude improvement over existing constraints. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2204.13249v1-abstract-full').style.display = 'none'; document.getElementById('2204.13249v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 27 April, 2022; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> April 2022. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">29 pages, 10 figures, submitted to Chinese Physics C</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2112.14450">arXiv:2112.14450</a> <span> [<a href="https://arxiv.org/pdf/2112.14450">pdf</a>, <a href="https://arxiv.org/format/2112.14450">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Phenomenology">hep-ph</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1007/JHEP06(2022)062">10.1007/JHEP06(2022)062 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Damping signatures at JUNO, a medium-baseline reactor neutrino oscillation experiment </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/hep-ex?searchtype=author&query=JUNO+collaboration"> JUNO collaboration</a>, <a href="/search/hep-ex?searchtype=author&query=Wang%2C+J">Jun Wang</a>, <a href="/search/hep-ex?searchtype=author&query=Liao%2C+J">Jiajun Liao</a>, <a href="/search/hep-ex?searchtype=author&query=Wang%2C+W">Wei Wang</a>, <a href="/search/hep-ex?searchtype=author&query=Abusleme%2C+A">Angel Abusleme</a>, <a href="/search/hep-ex?searchtype=author&query=Adam%2C+T">Thomas Adam</a>, <a href="/search/hep-ex?searchtype=author&query=Ahmad%2C+S">Shakeel Ahmad</a>, <a href="/search/hep-ex?searchtype=author&query=Ahmed%2C+R">Rizwan Ahmed</a>, <a href="/search/hep-ex?searchtype=author&query=Aiello%2C+S">Sebastiano Aiello</a>, <a href="/search/hep-ex?searchtype=author&query=Akram%2C+M">Muhammad Akram</a>, <a href="/search/hep-ex?searchtype=author&query=An%2C+F">Fengpeng An</a>, <a href="/search/hep-ex?searchtype=author&query=An%2C+Q">Qi An</a>, <a href="/search/hep-ex?searchtype=author&query=Andronico%2C+G">Giuseppe Andronico</a>, <a href="/search/hep-ex?searchtype=author&query=Anfimov%2C+N">Nikolay Anfimov</a>, <a href="/search/hep-ex?searchtype=author&query=Antonelli%2C+V">Vito Antonelli</a>, <a href="/search/hep-ex?searchtype=author&query=Antoshkina%2C+T">Tatiana Antoshkina</a>, <a href="/search/hep-ex?searchtype=author&query=Asavapibhop%2C+B">Burin Asavapibhop</a>, <a href="/search/hep-ex?searchtype=author&query=de+Andr%C3%A9%2C+J+P+A+M">Jo茫o Pedro Athayde Marcondes de Andr茅</a>, <a href="/search/hep-ex?searchtype=author&query=Auguste%2C+D">Didier Auguste</a>, <a href="/search/hep-ex?searchtype=author&query=Babic%2C+A">Andrej Babic</a>, <a href="/search/hep-ex?searchtype=author&query=Balashov%2C+N">Nikita Balashov</a>, <a href="/search/hep-ex?searchtype=author&query=Baldini%2C+W">Wander Baldini</a>, <a href="/search/hep-ex?searchtype=author&query=Barresi%2C+A">Andrea Barresi</a>, <a href="/search/hep-ex?searchtype=author&query=Basilico%2C+D">Davide Basilico</a>, <a href="/search/hep-ex?searchtype=author&query=Baussan%2C+E">Eric Baussan</a> , et al.

An excellent energy resolution and a large fiducial volume offer exciting opportunities for addressing many important topics in neutrino and astro-particle physics. With 6 years of data, the neutrino mass ordering can be determined at 3-4 sigma and three oscillation parameters can be measured to a precision of 0.6% or better by detecting reactor antineutrinos. With 10 years of data, DSNB could be observed at 3-sigma; a lower limit of the proton lifetime of 8.34e33 years (90% C.L.) can be set by searching for p->nu_bar K^+; detection of solar neutrinos would shed new light on the solar metallicity problem and examine the vacuum-matter transition region. A core-collapse supernova at 10 kpc would lead to ~5000 IBD and ~2000 (300) all-flavor neutrino-proton (electron) scattering events. Geo-neutrinos can be detected with a rate of ~400 events/year. We also summarize the final design of the JUNO detector and the key R&D achievements. All 20-inch PMTs have been tested. The average photon detection efficiency is 28.9% for the 15,000 MCP PMTs and 28.1% for the 5,000 dynode PMTs, higher than the JUNO requirement of 27%. Together with the >20 m attenuation length of LS, we expect a yield of 1345 p.e. per MeV and an effective energy resolution of 3.02%/\sqrt{E (MeV)}$ in simulations. The underwater electronics is designed to have a loss rate <0.5% in 6 years. With degassing membranes and a micro-bubble system, the radon concentration in the 35-kton water pool could be lowered to <10 mBq/m^3. Acrylic panels of radiopurity <0.5 ppt U/Th are produced. The 20-kton LS will be purified onsite. Singles in the fiducial volume can be controlled to ~10 Hz. The JUNO experiment also features a double calorimeter system with 25,600 3-inch PMTs, a LS testing facility OSIRIS, and a near detector TAO. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2104.02565v2-abstract-full').style.display = 'none'; document.getElementById('2104.02565v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 12 May, 2021; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 6 April, 2021; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> April 2021. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">A review paper with 78 pages and 32 figures. v2: minor revision.

The Jiangmen Underground Neutrino Observatory (JUNO) experiment, a 20 kton liquid scintillator detector with excellent energy resolution is currently under construction in China. JUNO will be able to detect several atmospheric neutrinos per day given the large volume. A study on the JUNO detection and reconstruction capabilities of atmospheric $谓_e$ and $谓_渭$ fluxes is presented in this paper. In this study, a sample of atmospheric neutrino Monte Carlo events has been generated, starting from theoretical models, and then processed by the detector simulation. The excellent timing resolution of the 3'' PMT light detection system of JUNO detector and the much higher light yield for scintillation over Cherenkov allow to measure the time structure of the scintillation light with very high precision. Since $谓_e$ and $谓_渭$ interactions produce a slightly different light pattern, the different time evolution of light allows to discriminate the flavor of primary neutrinos. A probabilistic unfolding method has been used, in order to infer the primary neutrino energy spectrum from the detector experimental observables. The simulated spectrum has been reconstructed between 100 MeV and 10 GeV, showing a great potential of the detector in the atmospheric low energy region. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2103.09908v3-abstract-full').style.display = 'none'; document.getElementById('2103.09908v3-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 12 October, 2021; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 17 March, 2021; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> March 2021. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">25 pages, 9 figures</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Eur.

They produce many of the chemical elements necessary for life to exist and their remnants -- neutron stars and black holes -- are interesting astrophysical objects in their own right. However, despite millennia of observations and almost a century of astrophysical study, the explosion mechanism of core-collapse supernovae is not yet well understood. Hyper-Kamiokande is a next-generation neutrino detector that will be able to observe the neutrino flux from the next galactic core-collapse supernova in unprecedented detail. We focus on the first 500 ms of the neutrino burst, corresponding to the accretion phase, and use a newly-developed, high-precision supernova event generator to simulate Hyper-Kamiokande's response to five different supernova models. We show that Hyper-Kamiokande will be able to distinguish between these models with high accuracy for a supernova at a distance of up to 100 kpc. Once the next galactic supernova happens, this ability will be a powerful tool for guiding simulations towards a precise reproduction of the explosion mechanism observed in nature. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2101.05269v2-abstract-full').style.display = 'none'; document.getElementById('2101.05269v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 20 July, 2021; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 13 January, 2021; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> January 2021. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">21 pages, 7 figures.

The detector which has an 8.4~times larger effective volume than its predecessor will be located along the T2K neutrino beamline and utilize an upgraded J-PARC beam with 2.6~times beam power. Hyper-K's low energy threshold combined with the very large fiducial volume make the detector unique, that is expected to acquire an unprecedented exposure of 3.8~Mton$\cdot$year over a period of 20~years of operation. Hyper-Kamiokande combines an extremely diverse science program including nucleon decays, long-baseline neutrino oscillations, atmospheric neutrinos, and neutrinos from astrophysical origins. The scientific scope of this program is highly complementary to liquid-argon detectors for example in sensitivity to nucleon decay channels or supernova detection modes. Hyper-Kamiokande construction has started in early 2020 and the experiment is expected to start operations in 2027. The Hyper-Kamiokande collaboration is presently being formed amongst groups from 19 countries including the United States, whose community has a long history of making significant contributions to the neutrino physics program in Japan. US physicists have played leading roles in the Kamiokande, Super-Kamiokande, EGADS, K2K, and T2K programs. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2009.00794v1-abstract-full').style.display = 'none'; document.getElementById('2009.00794v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 1 September, 2020; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> September 2020. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">6 pages, prepared as Snowmass2021 LOI</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2007.00314">arXiv:2007.00314</a> <span> [<a href="https://arxiv.org/pdf/2007.00314">pdf</a>, <a href="https://arxiv.org/format/2007.00314">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> </div> </div> <p class="title is-5 mathjax"> Optimization of the JUNO liquid scintillator composition using a Daya Bay antineutrino detector </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/hep-ex?searchtype=author&query=Bay%2C+D">Daya Bay</a>, <a href="/search/hep-ex?searchtype=author&query=collaborations%2C+J">JUNO collaborations</a>, <a href="/search/hep-ex?searchtype=author&query=%3A"> :</a>, <a href="/search/hep-ex?searchtype=author&query=Abusleme%2C+A">A.

The optical properties of the new LS in various compositions were studied by replacing the gadolinium-loaded LS in one antineutrino detector. The concentrations of the fluor, PPO, and the wavelength shifter, bis-MSB, were increased in 12 steps from 0.5 g/L and <0.01 mg/L to 4 g/L and 13 mg/L, respectively. The numbers of total detected photoelectrons suggest that, with the optically purified solvent, the bis-MSB concentration does not need to be more than 4 mg/L. To bridge the one order of magnitude in the detector size difference between Daya Bay and JUNO, the Daya Bay data were used to tune the parameters of a newly developed optical model. Then, the model and tuned parameters were used in the JUNO simulation. This enabled to determine the optimal composition for the JUNO LS: purified solvent LAB with 2.5 g/L PPO, and 1 to 4 mg/L bis-MSB. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2007.00314v1-abstract-full').style.display = 'none'; document.getElementById('2007.00314v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 1 July, 2020; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> July 2020. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">13 pages, 8 figures</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2006.11760">arXiv:2006.11760</a> <span> [<a href="https://arxiv.org/pdf/2006.11760">pdf</a>, <a href="https://arxiv.org/format/2006.11760">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Phenomenology">hep-ph</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> </div> </div> <p class="title is-5 mathjax"> Feasibility and physics potential of detecting $^8$B solar neutrinos at JUNO </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/hep-ex?searchtype=author&query=JUNO+collaboration"> JUNO collaboration</a>, <a href="/search/hep-ex?searchtype=author&query=Abusleme%2C+A">Angel Abusleme</a>, <a href="/search/hep-ex?searchtype=author&query=Adam%2C+T">Thomas Adam</a>, <a href="/search/hep-ex?searchtype=author&query=Ahmad%2C+S">Shakeel Ahmad</a>, <a href="/search/hep-ex?searchtype=author&query=Aiello%2C+S">Sebastiano Aiello</a>, <a href="/search/hep-ex?searchtype=author&query=Akram%2C+M">Muhammad Akram</a>, <a href="/search/hep-ex?searchtype=author&query=Ali%2C+N">Nawab Ali</a>, <a href="/search/hep-ex?searchtype=author&query=An%2C+F">Fengpeng An</a>, <a href="/search/hep-ex?searchtype=author&query=An%2C+G">Guangpeng An</a>, <a href="/search/hep-ex?searchtype=author&query=An%2C+Q">Qi An</a>, <a href="/search/hep-ex?searchtype=author&query=Andronico%2C+G">Giuseppe Andronico</a>, <a href="/search/hep-ex?searchtype=author&query=Anfimov%2C+N">Nikolay Anfimov</a>, <a href="/search/hep-ex?searchtype=author&query=Antonelli%2C+V">Vito Antonelli</a>, <a href="/search/hep-ex?searchtype=author&query=Antoshkina%2C+T">Tatiana Antoshkina</a>, <a href="/search/hep-ex?searchtype=author&query=Asavapibhop%2C+B">Burin Asavapibhop</a>, <a href="/search/hep-ex?searchtype=author&query=de+Andr%C3%A9%2C+J+P+A+M">Jo茫o Pedro Athayde Marcondes de Andr茅</a>, <a href="/search/hep-ex?searchtype=author&query=Auguste%2C+D">Didier Auguste</a>, <a href="/search/hep-ex?searchtype=author&query=Babic%2C+A">Andrej Babic</a>, <a href="/search/hep-ex?searchtype=author&query=Baldini%2C+W">Wander Baldini</a>, <a href="/search/hep-ex?searchtype=author&query=Barresi%2C+A">Andrea Barresi</a>, <a href="/search/hep-ex?searchtype=author&query=Baussan%2C+E">Eric Baussan</a>, <a href="/search/hep-ex?searchtype=author&query=Bellato%2C+M">Marco Bellato</a>, <a href="/search/hep-ex?searchtype=author&query=Bergnoli%2C+A">Antonio Bergnoli</a>, <a href="/search/hep-ex?searchtype=author&query=Bernieri%2C+E">Enrico Bernieri</a>, <a href="/search/hep-ex?searchtype=author&query=Biare%2C+D">David Biare</a> , et al.

Some of JUNO's features make it an excellent experiment for $^8$B solar neutrino measurements, such as its low-energy threshold, its high energy resolution compared to water Cherenkov detectors, and its much large target mass compared to previous liquid scintillator detectors. In this paper we present a comprehensive assessment of JUNO's potential for detecting $^8$B solar neutrinos via the neutrino-electron elastic scattering process. A reduced 2~MeV threshold on the recoil electron energy is found to be achievable assuming the intrinsic radioactive background $^{238}$U and $^{232}$Th in the liquid scintillator can be controlled to 10$^{-17}$~g/g. With ten years of data taking, about 60,000 signal and 30,000 background events are expected. This large sample will enable an examination of the distortion of the recoil electron spectrum that is dominated by the neutrino flavor transformation in the dense solar matter, which will shed new light on the tension between the measured electron spectra and the predictions of the standard three-flavor neutrino oscillation framework. If $螖m^{2}_{21}=4.8\times10^{-5}~(7.5\times10^{-5})$~eV$^{2}$, JUNO can provide evidence of neutrino oscillation in the Earth at the about 3$蟽$~(2$蟽$) level by measuring the non-zero signal rate variation with respect to the solar zenith angle. Moveover, JUNO can simultaneously measure $螖m^2_{21}$ using $^8$B solar neutrinos to a precision of 20\% or better depending on the central value and to sub-percent precision using reactor antineutrinos. A comparison of these two measurements from the same detector will help elucidate the current tension between the value of $螖m^2_{21}$ reported by solar neutrino experiments and the KamLAND experiment. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2006.11760v1-abstract-full').style.display = 'none'; document.getElementById('2006.11760v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 21 June, 2020; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> June 2020. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">29 pages, 14 plots, 7 tables</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2005.08745">arXiv:2005.08745</a> <span> [<a href="https://arxiv.org/pdf/2005.08745">pdf</a>, <a href="https://arxiv.org/format/2005.08745">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Nuclear Experiment">nucl-ex</span> </div> </div> <p class="title is-5 mathjax"> TAO Conceptual Design Report: A Precision Measurement of the Reactor Antineutrino Spectrum with Sub-percent Energy Resolution </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/hep-ex?searchtype=author&query=JUNO+Collaboration"> JUNO Collaboration</a>, <a href="/search/hep-ex?searchtype=author&query=Abusleme%2C+A">Angel Abusleme</a>, <a href="/search/hep-ex?searchtype=author&query=Adam%2C+T">Thomas Adam</a>, <a href="/search/hep-ex?searchtype=author&query=Ahmad%2C+S">Shakeel Ahmad</a>, <a href="/search/hep-ex?searchtype=author&query=Aiello%2C+S">Sebastiano Aiello</a>, <a href="/search/hep-ex?searchtype=author&query=Akram%2C+M">Muhammad Akram</a>, <a href="/search/hep-ex?searchtype=author&query=Ali%2C+N">Nawab Ali</a>, <a href="/search/hep-ex?searchtype=author&query=An%2C+F">Fengpeng An</a>, <a href="/search/hep-ex?searchtype=author&query=An%2C+G">Guangpeng An</a>, <a href="/search/hep-ex?searchtype=author&query=An%2C+Q">Qi An</a>, <a href="/search/hep-ex?searchtype=author&query=Andronico%2C+G">Giuseppe Andronico</a>, <a href="/search/hep-ex?searchtype=author&query=Anfimov%2C+N">Nikolay Anfimov</a>, <a href="/search/hep-ex?searchtype=author&query=Antonelli%2C+V">Vito Antonelli</a>, <a href="/search/hep-ex?searchtype=author&query=Antoshkina%2C+T">Tatiana Antoshkina</a>, <a href="/search/hep-ex?searchtype=author&query=Asavapibhop%2C+B">Burin Asavapibhop</a>, <a href="/search/hep-ex?searchtype=author&query=de+Andr%C3%A9%2C+J+P+A+M">Jo茫o Pedro Athayde Marcondes de Andr茅</a>, <a href="/search/hep-ex?searchtype=author&query=Auguste%2C+D">Didier Auguste</a>, <a href="/search/hep-ex?searchtype=author&query=Babic%2C+A">Andrej Babic</a>, <a href="/search/hep-ex?searchtype=author&query=Baldini%2C+W">Wander Baldini</a>, <a href="/search/hep-ex?searchtype=author&query=Barresi%2C+A">Andrea Barresi</a>, <a href="/search/hep-ex?searchtype=author&query=Baussan%2C+E">Eric Baussan</a>, <a href="/search/hep-ex?searchtype=author&query=Bellato%2C+M">Marco Bellato</a>, <a href="/search/hep-ex?searchtype=author&query=Bergnoli%2C+A">Antonio Bergnoli</a>, <a href="/search/hep-ex?searchtype=author&query=Bernieri%2C+E">Enrico Bernieri</a>, <a href="/search/hep-ex?searchtype=author&query=Biare%2C+D">David Biare</a> , et al.

The reactor antineutrino spectrum will be measured with sub-percent energy resolution, to provide a reference spectrum for future reactor neutrino experiments, and to provide a benchmark measurement to test nuclear databases. A spherical acrylic vessel containing 2.8 ton gadolinium-doped liquid scintillator will be viewed by 10 m^2 Silicon Photomultipliers (SiPMs) of >50% photon detection efficiency with almost full coverage. The photoelectron yield is about 4500 per MeV, an order higher than any existing large-scale liquid scintillator detectors. The detector operates at -50 degree C to lower the dark noise of SiPMs to an acceptable level. The detector will measure about 2000 reactor antineutrinos per day, and is designed to be well shielded from cosmogenic backgrounds and ambient radioactivities to have about 10% background-to-signal ratio.

Thanks to the anti-neutrinos produced by the nearby nuclear power plants, JUNO will primarily study the neutrino mass hierarchy, one of the open key questions in neutrino physics. One key ingredient for the success of the measurement is to use high speed, high resolution sampling electronics located very close to the detector signal. Linearity in the response of the electronics in another important ingredient for the success of the experiment. During the initial design phase of the electronics, a custom design, with the Front-End and Read-Out electronics located very close to the detector analog signal has been developed and successfully tested. The present paper describes the electronics structure and the first tests performed on the prototypes. The electronics prototypes have been tested and they show good linearity response, with a maximum deviation of 1.3% over the full dynamic range (1-1000 p.e.), fulfilling the JUNO experiment requirements. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2003.08339v2-abstract-full').style.display = 'none'; document.getElementById('2003.08339v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 17 May, 2020; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 18 March, 2020; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> March 2020. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">20 pages, 15 figures</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/1912.06178">arXiv:1912.06178</a> <span> [<a href="https://arxiv.org/pdf/1912.06178">pdf</a>, <a href="https://arxiv.org/format/1912.06178">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1088/1748-0221/14/12/C12010">10.1088/1748-0221/14/12/C12010 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Study of the effects of radiation on the CMS Drift Tubes Muon Detector for the HL-LHC </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/hep-ex?searchtype=author&query=Abbiendi%2C+G">G.

However, full CMS simulations have shown almost no impact in the muon reconstruction efficiency over the full barrel acceptance and for the full integrated luminosity. A second spare DT chamber was moved inside the GIF++ bunker in October 2017. The chamber was being irradiated at lower acceleration factors, and only 2 out of the 12 layers of the chamber were switched at working voltage when the radioactive source was active, being the other layers in standby. In this way the other non-aged layers are used as reference and as a precise and unbiased telescope of muon tracks for the efficiency computation of the aged layers of the chamber, when set at working voltage for measurements. An integrated dose equivalent to two times the expected integrated luminosity of the HL-LHC run has been absorbed by this second spare DT chamber and the final impact on the muon reconstruction efficiency is under study. Direct inspection of some extracted aged anode wires presented a melted resistive deposition of materials. Investigation on the outgassing of cell materials and of the gas components used at the GIF++ are underway. Strategies to mitigate the ageing effects are also being developed. From the long irradiation measurements of the second spare DT chamber, the effects of radiation in the performance of the DTs expected during the HL-LHC run will be presented. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1912.06178v1-abstract-full').style.display = 'none'; document.getElementById('1912.06178v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 12 December, 2019; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> December 2019. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">10 pages, 7 figures, to be published in JINST, editor I.

It is located 53 km away from both Yangjiang and Taishan Nuclear Power Plants in Guangdong, China. The experimental hall, spanning more than 50 meters, is under a granite mountain of over 700 m overburden. Within six years of running, the detection of reactor antineutrinos can resolve the neutrino mass hierarchy at a confidence level of 3-4$蟽$, and determine neutrino oscillation parameters $\sin^2胃_{12}$, $螖m^2_{21}$, and $|螖m^2_{ee}|$ to an accuracy of better than 1%. The JUNO detector can be also used to study terrestrial and extra-terrestrial neutrinos and new physics beyond the Standard Model. The central detector contains 20,000 tons liquid scintillator with an acrylic sphere of 35 m in diameter. $\sim$17,000 508-mm diameter PMTs with high quantum efficiency provide $\sim$75% optical coverage. The current choice of the liquid scintillator is: linear alkyl benzene (LAB) as the solvent, plus PPO as the scintillation fluor and a wavelength-shifter (Bis-MSB). The number of detected photoelectrons per MeV is larger than 1,100 and the energy resolution is expected to be 3% at 1 MeV. The calibration system is designed to deploy multiple sources to cover the entire energy range of reactor antineutrinos, and to achieve a full-volume position coverage inside the detector. The veto system is used for muon detection, muon induced background study and reduction. It consists of a Water Cherenkov detector and a Top Tracker system. The readout system, the detector control system and the offline system insure efficient and stable data acquisition and processing. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1508.07166v2-abstract-full').style.display = 'none'; document.getElementById('1508.07166v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 28 September, 2015; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 28 August, 2015; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> August 2015. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">328 pages, 211 figures</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/1306.5655">arXiv:1306.5655</a> <span> [<a href="https://arxiv.org/pdf/1306.5655">pdf</a>, <a href="https://arxiv.org/format/1306.5655">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Instrumentation and Detectors">physics.ins-det</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="High Energy Physics - Experiment">hep-ex</span> </div> </div> <p class="title is-5 mathjax"> SuperB Technical Design Report </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/hep-ex?searchtype=author&query=SuperB+Collaboration"> SuperB Collaboration</a>, <a href="/search/hep-ex?searchtype=author&query=Baszczyk%2C+M">M.

The SuperB asymmetric collider, which was to be constructed on the Tor Vergata campus near the INFN Frascati National Laboratory, was designed to operate both at the Upsilon(4S) center-of-mass energy with a luminosity of 10^{36} cm^{-2}s^{-1} and at the tau/charm production threshold with a luminosity of 10^{35} cm^{-2}s^{-1}. This high luminosity, producing a data sample about a factor 100 larger than present B Factories, would allow investigation of new physics effects in rare decays, CP Violation and Lepton Flavour Violation. This document details the detector design presented in the Conceptual Design Report (CDR) in 2007. The R&D and engineering studies performed to arrive at the full detector design are described, and an updated cost estimate is presented. A combination of a more realistic cost estimates and the unavailability of funds due of the global economic climate led to a formal cancelation of the project on Nov 27, 2012. <a class="is-size-7"
